“I was pleasantly surprised at how quickly the response was . Dustin, my technician was here within 2 hours. He was polite, clean and professional. He explained everything he tested and fortunately only found a small problem which he fixed in minutes. It's very refreshing that he did not try to be a salesman. One Hour has just made us loyal customers!”

“My A/C blew out Friday night. I tried calling a couple places and One Hour were the earliest appointment I could get from anyone. She showed up at noon on Saturday. The tech was amazing! She thought it was a blown capacitor, went to take a look and that was it. Super fast repair. She offered the membership like all the companies do and given how good this experience was, I opted in. I thought pricing was fair all things considered. Would recommend!”

“We called for service, was given same day appointment. James called and let us know he was on the way. James is very friendly, professional and knowledgeable. The company sent a text with James’s picture so that we knew exactly who to expect. Would highly recommend this company and this technician.”

“5 Stars – Exceptional Service from Ruben at One Hour Heating and Air Conditioning!
We had an outstanding experience with Ruben from One Hour Heating and Air Conditioning here in Longs, SC. Our old AC unit was over 15 years old, inefficient, and breaking down frequently. Ruben did a thorough inspection, explained everything clearly, and showed us why replacing the unit was the smartest and most cost-effective choice.
He was professional, honest, and never pushy—just truly helpful. He guided us through selecting the right new system for our home and made the whole process smooth and stress-free.
We’re so grateful to Ruben for his expertise and excellent service. Highly recommend One Hour Heating and Air Conditioning to anyone in the Longs area!
William and Rita Maloney”

“My wife and I purchased a house, and requested a review of our A/C system to be sure it was working correctly. We were very pleased with Kameron, our technician, who was very professional and knowledgeable. We signed up for a two year membership, and feel good knowing that if any problems arise, we can get the service and support we need.”

“Austin did a great job! He showed up as promised and got me set up with everything I needed to get my AC running again. He went above and beyond to explain how everything works and even pointed out some services that will save money in the long run. I highly recommend!”

“Our experience with Stephen was great. He arrived before the expected arrival time and arrived in company uniform with name tag that matched his picture that he sent via text link prior to his arrival. Upon arrival to our home, he put on shoe covers, introduced himself, pointed to his badge and explained why he was here. He thoroughly explained what he did and why and the different cost options; he even found a military discount because my husband is a veteran. Stephen was very knowledgeable and quickly found the problem with our home air conditioning units. He was very professional the entire time. I highly recommend Stephen from One Hour Air.”

“I love Duggans!! I had them install 3 mini splits from them. They promised me my bill would drop to half or less, from standard units that take up half of your house with duck work running everywhere as well as the giant unit outside. They were right! From $500 a month to $150 to $180 depending on the cold or heat here in SC!! What a savings!! My home is 1000 sq ft. We are comfortable all year long. If there's a problem, they come out right away with techs that really know their stuff & get it done right! Very respectful to you & your property. Prices are reasonable as well. Some thing that is rare in companies now a days. I have them on speed dial. Mr Sparky the other side of Duggans is the best as well! They completely rewired my entire home & put in a new main box bringing everything up to code. These two companies are what businesses are supposed to be like. 10 stars to each! Like I said, I have them on speed dial! But rarely have to call as there products & workmanship rarely need repairs. Ya they're that good! Call them for any HAVAC or electrical work you need done. You won't be disappointed!!”
